السلام عليكم You reminded me of the book "Manaqib `Umar bin al-Khattab (ra)" by ibn al-Jawzi (rah), the book is very famous, accepted and recommended by many scholars, it contains narrations of virtue for Ameer al-Mu'mineen (ra), HOWEVER the version we have today is unfortunately a summary of the original version, in other words it contains all the narrations of virtue but with no chains of transmission, they have been removed to make the book shorter. Everyone reads it although the authenticity of the texts is unknown, no one said "Well I'm not gonna read any narration unless I know it's gonna be SAHIH." that is unheard of. Behind the scenes, the scholars had a really hard time trying to authenticate the narrations, basically they try looking for the same narrations or similar ones in other books, and they would check the Isnads in other books... But miraculously just a couple of weeks ago, a version of "Manaqib `Umar" of Ibn al-Jawzi (rah) was found in an old library, AND IT CONTAINS ALL THE CHAINS They found the complete book and I can't wait for this version to get published, I have a bit of a hobby myself to see how authentic the narrations are =p
